This algorithm helps you to swap cases.
|
|
|
|
User will give input and then program will perform swap cases.
|
|
|
|
In other words, convert all lowercase letters to uppercase letters and vice versa.
|
|
For example:
|
|
1. Please input sentence: Algorithm.Python@89
|
|
aLGORITHM.pYTHON@89
|
|
2. Please input sentence: github.com/mayur200
|
|
GITHUB.COM/MAYUR200
